[0020] The technical solutions of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0021] The embodiment of the present application discloses a tire cleaning device for a mining watering truck. Referring to Figure 1 ​​The application relates to a tire cleaning device for a mine spraying vehicle, which comprises a cleaning seat 1 installed on a vehicle frame, a cleaning strip 2 hinged to the cleaning seat 1, and a torsional elastic element 3 arranged at the hinge part of the cleaning strip 2 and the cleaning seat 1.

[0022] When the mine spraying vehicle normally runs, the cleaning strip 2 keeps the initial position of extending to the gap between the double tires under the action of the torsional elastic element 3, and the cleaning strip 2 does not interfere with the normal rotation of the tires due to the certain gap between the cleaning strip 2 and the tire surface. When the gap between the double tires is clamped with impurities such as mine slag and stones, the impurities first contact the lower end of the cleaning strip 2 and press the lower end of the cleaning strip 2 due to the extension of the lower end of the cleaning strip 2 to the gap between the double tires along with the rotation of the double tires. The cleaning strip 2 is hinged to the cleaning seat 1, and the hinge part is provided with the torsional elastic element 3. The cleaning strip 2 is turned towards the wheel shaft of the double tires along with the pressing of the impurities. The torsional elastic element 3 is twisted, the pressing degree is higher, the torsional angle of the torsional elastic element 3 is larger, and the stored elastic potential energy is more. In the process, the lower end of the cleaning strip 2 moves relative to the surface of the impurities under the action of the elastic potential energy stored in the torsional elastic element 3, and the impurities are pushed to the outside of the tire gap. For some small mine slag particles, the scraping action can directly scrape them out of the tire gap; for larger stones, the pushing action helps to change the position, so that the stones are more easily removed by subsequent cleaning actions.

[0023] Through the cooperation of the cleaning strip 2 and the torsional elastic element 3, the impurities such as mine slag and stones clamped in the gap are effectively scraped, pushed and removed during the rotation of the double tires, so that the tire gap is kept clean, the normal use of the tires is ensured, and the driving safety of the spraying vehicle is ensured. The existing tire cleaning device cannot realize real-time processing of the gap between the double tires, which easily leads to abnormal wear of the tires, imbalance of the tire pressure and even the risk of tire burst.

[0024] Specifically, referring to Figure 1 A plurality of through holes 11 are formed in the cleaning seat 1, and a plurality of mounting holes corresponding to the through holes 11 are formed in the vehicle frame. The cleaning seat 1 is fixed on the vehicle frame through bolts.

[0025] The cleaning seat 1 is fixed by bolts, so that the installation and disassembly process is relatively simple. During installation, only the through hole 11 on the cleaning seat 1 is aligned with the mounting hole on the frame, then the bolt is inserted and the nut is tightened. When maintenance is required, the cleaning strip 2 is replaced, or the frame is overhauled, the cleaning seat 1 can also be easily disassembled, improving the maintainability and flexibility of the equipment.

[0026] And, referring to Figure 1 , the cleaning seat 1 is provided with a limiting strip 12 on the side facing the cleaning strip 2. When the cleaning strip 2 is turned over on the cleaning seat 1 to contact the limiting strip 12, the lower end of the cleaning strip 2 will contact the axle of the double-tired vehicle.

[0027] During the driving of the mine sprinkler, the tire cleaning device needs to adapt to different road conditions and tire rotation. When the cleaning strip 2 is pressed by a large external force, the presence of the limiting strip 12 can prevent the cleaning strip 2 from being excessively turned over, causing the torsional elastic element 3 to be excessively twisted and even damaged; at the same time, it can also avoid the collision between the cleaning strip 2 and the tire axle, causing damage to the cleaning strip 2 or the axle.

[0028] And, referring to Figures 1 to 3 , a compression spring 21 is provided between the limiting strip 12 and the cleaning strip 2. The compression spring 21 has sufficient rigidity and elastic recovery ability. When the cleaning strip 2 is pressed by impurities and turned over around the hinge shaft towards the limiting strip 12, the compression spring 21 can absorb and buffer this part of the impact force, reducing damage to the cleaning strip 2, the limiting strip 12 and the torsional elastic element 3 caused by instantaneous impact, effectively prolonging the service life of the device; and when the external force disappears, the compression spring 21 will release its stored elastic potential energy, assisting the torsional elastic element 3 to make the cleaning strip 2 recover to the initial position more quickly. This helps to improve the working efficiency of the cleaning device, so that the cleaning strip 2 can clean the impurities in the tire gap in the next time.

[0029] Further, referring to Figures 1 to 3 , the limiting strip 12 is provided with an upper sleeve 123, and the cleaning strip 2 is hingedly provided with a lower sleeve 22 corresponding to the upper sleeve 123. The outer diameter of the lower sleeve 22 is smaller than the inner diameter of the upper sleeve 123, and the compression spring 21 is inserted into the relatively arranged upper sleeve 123 and lower sleeve 22.

[0030] The upper sleeve 123 and the lower sleeve 22 can provide precise positioning and guiding for the compression spring 21. During the overturning process of the cleaning strip 2, the upper sleeve 123 and the lower sleeve 22 can ensure that the compression spring 21 always maintains the correct position and direction during the compression and release process, avoiding the compression spring 21 from being offset or twisted, thereby ensuring the normal operation of the cleaning device. In addition, the upper sleeve 123 and the lower sleeve 22 can also protect the compression spring 21, reduce the direct contact of the compression spring 21 with the external environment, prevent the compression spring 21 from being eroded by dust, sundries, moisture, etc., reduce the risk of rust, wear and damage of the compression spring 21, and prolong the service life of the compression spring 21.

[0031] Meanwhile, referring to Figures 2 to 4 The upper sleeve 123 can be detachably installed on the limiting strip 12. In this way, when the compression spring 21 needs to be replaced due to damage, the operator can easily take and place the compression spring 21 by detaching the upper sleeve 123 from the limiting strip 12, thereby reducing the operation difficulty and improving the replacement efficiency.

[0032] In addition, referring to Figures 2 to 4 The upper sleeve 123 is coaxially and fixedly connected to the screw 122 at the end of the limiting strip 12. The upper sleeve 123 is provided with a plurality of openings near the end of the screw 122, which facilitates the rotation of the upper sleeve 123. The limiting strip 12 is provided with a threaded hole 121 corresponding to the screw 122, and the screw 122 is threadedly matched with the threaded hole 121.

[0033] When the upper sleeve 123 or the compression spring 21 needs to be replaced or maintained, a suitable tool such as a wrench is used to align the opening on the upper sleeve 123 and rotate, and the screw 122 is rotated out of the threaded hole 121, so that the upper sleeve 123 can be detached from the limiting strip 12. The disassembly process is convenient and fast, and does not require complex tools and operations.

[0034] The implementation principle of the tire cleaning device for the mining sprinkler vehicle according to the embodiment of the present application is as follows:

[0035] When the mine sprinkler is running normally, the cleaning strip 2 is kept in the initial position with the lower end extending into the gap between the dual tires under the action of the torsional elastic member 3, and since the cleaning strip 2 keeps a certain gap with the tire surface, it will not interfere with the normal rotation of the tire. When the gap between the dual tires is clamped with impurities such as mine slag and stones, since the lower end of the cleaning strip 2 extends into the gap between the dual tires, with the rotation of the dual tires, the impurities will first contact the lower end of the cleaning strip 2, and an extrusion force is generated on the lower end of the cleaning strip 2. Since the hinged part of the cleaning strip 2 and the cleaning seat 1 is provided with the torsional elastic member 3, under the extrusion of the impurities, the cleaning strip 2 will be flipped around the hinge shaft towards the direction close to the wheel shaft of the dual tires. With the flipping of the cleaning strip 2 under the extrusion of the impurities, the torsional elastic member 3 starts to be twisted, the greater the extrusion force, the greater the twisting angle of the torsional elastic member 3, and the more the elastic potential energy stored. In this process, under the action of the elastic potential energy stored in the torsional elastic member 3, the lower end of the cleaning strip 2 will move relative to the surface of the impurities, and push the impurities to move towards the outside of the tire gap. For some smaller mine slag particles, the scraping action can directly scrape them out of the tire gap; for larger stones, the pushing action helps to change their position, making them easier to be removed by subsequent cleaning actions.

[0036] Through the cooperation of the cleaning strip 2 and the torsional elastic member 3, the impurities such as mine slag and stones clamped in the gap are effectively scraped, pushed and removed during the rotation of the dual tires, so as to keep the tire gap clean and ensure the normal use of the tire and the driving safety of the sprinkler. The problem that the existing tire cleaning device cannot real-time process the gap of the dual tires, which easily leads to abnormal wear of the tire, imbalance of tire pressure and even risk of tire burst, is effectively improved.
